The Republic of Gamers MARS II, detailed earlier, is a new custom dual-GF110 based graphics card in the works at ASUS. Here are some of its first pictures, revealing a monstrosity that's about as long as a Radeon HD 5970, a couple of inches higher, and three slots thick. Its cooler sticks to the black+red color scheme in use with ASUS ROG products for a while now, and uses an intricate cutout design.

The shroud suspends two 120 mm high-sweep fans that blow air on to two heatsinks with highly dense aluminum fin arrays to which heat is fed by copper heat pipes. The card draws power from three 8-pin PCI-Express power connectors. The card uses two NVIDIA GF110 GPUs with the same core configuration and clock profile as GeForce GTX 580, effectively making MARS II a dual-GTX 580, which also provides the overclocking headroom of a GTX 580, something impossible on a NVIDIA GeForce GTX 590.

in case it's unclear: the little red 100% fan switch is used to switch the fan speed to 100% without any software - great for overclocking. pressing it again returns to normal temperature controlled fan speed.

doubt it, since it's only 3x8pin connector, its not going to be over 400w after you factor in overhead. to be realistic, the msi 480gtx had 2x8pin+1x6pin(450w), and in reality it had TDP of only 275w. so i'm guessing somewhere around 400w TDP for this card (realistically speaking).

Those are specifications limits. Nobody follows them in this segment, you can overdraw from the cable by even 40%, it won't burn up. ASUS will recommend what PSU Wattage you'll need. There are many examples of cards from every segment overdrawing from connectors and slots.
